EXHAUST-NOZZLE FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 310,769, dated January 13, 1885'.

Application filed November 20, 1884. (No model.)

To all whom it may concern.-

Be it known that Josnrn Wornrnx, deceased, late of the city, county, and State of New York, did during his life-time invent a certain new and useful Improvement in Exhaust-Nozzles for Locomotives, 820., of which the following is a specification.

This improvement,while designed more particularly to meet the needs of locomotiveserv- 1c ice, is also adapted for use in traction-engines, marine engines, 85c. The more usual Way of arranging exhaust-nozzles in locomotives has been to arrange the two nozzles side by side in the smoke-box below the smoke- I 5 stack. This arrangement brings the nozzles out of line with the center line of the stack, causing the exhaust-steam to strike one side or the other of the stack, thus decreasing its velocity and causing part of it to be left he hind, with the result of destroying the needed vacuum in the smoke-box. To remove these objections it has been essayed to arrange the two nozzles concentrically with one another; but such arrangements have been defective in that steam has not been fully availed of to exhaust or carry off the gaseous products of combustion.

It was with a view to overcome these difficulties that the said WVOTAPEK devised his improvement. To this end he combined with the smoke-stack and two concentric exhaustnozzles a receiving-cone located axially with respect to the nozzles and the smoke-stack, and communicating both at top and bottom with the interior of the smoke-box. In this way the exhaust steam from both nozzles was caused to flow up centrally to and through the receivingcone and the smoke-stack, doing its work without material decrease of velocity, and carrying off the gaseous products of combustion sucked up with it both from below and from above the receiving-cone, thus preserving the needed vacuum without necessitating a contraction of the nozzles, which latter would result, as is well known, in backpressure in the cylinders and in other serious drawbacks.

The nature of the improvement will be readily understood by reference to the accompanyin g drawing,which represents invcrtical trans- I verse section, partly in elevation, a locomotive smoke-box containing the improvement.

D is the smoke-box. C is the smoke-stack. o are the live-steam pipes, leading, as usual, to the engine-cylinders. A B are the exhauststeam nozzles communicating with the pipes at b,which lead the exhaust-steam from the cylinders in the usual way. The nozzle A is tubu lar. It is located in the lower part of the smokebox, and its axis is on the prolongation of the 6c axis of the smoke-stack 0 above. The exhaust: nozzle 13 surrounds and is concentric with the nozzle A, as shown. Intermediate between the smoke-stack and the exhaust-nozzles is the receivingcone E, having its axis on the prolon- 6g gation of the axes of the two nozzles and the smoke-stack. It is supported in position by any suitable meansin this instance by legs d, attached to the outer nozzle, B--and it opens both at its base and at its top into the inte- 7 rior of the s1noke-box. Exhaust-steam from either nozzle passes centrally up to and through the receiving-cone and smoke-stack, sucking up with it the smoke and gaseous products of combustion both from below the base and fromabove the top of the cone, much after the fashion of an ejector.

WVhat is claimed herein as the invention of the said J osnrn WorAPnK is- The combination, with the smoke box or 8( chamber and smoke-stack, of the two concentric exhaust-nozzles having their axes on the prolongation of the axis of the smoke-stack, and the receiving-cone intermediate between and located in line with the two nozzles and the smoke-stack, and communicating at its base and top with the interior of the smoke box, as and for the purposes hereinbefore set forth.

In testimony whereof I, BERTHA WOTAPEK, 9c administratrix of the estate of the late J OSEPH \VOTAPEK, deceased, have hereunto set my hand this 18th day of November, 1884.
